IRT1 — Brassica napus

Summary

BnIRT1 (DARMORV10_C03P82450.1) on chromosome C03 of oilseed rape encodes a ZIP family metal transporter with iron channel activity and transmembrane transporter activities for copper, manganese, zinc, and cadmium ions. It also exhibits phosphoinositide, ubiquitin, mRNA, and protein binding. The gene is associated with metal homeostasis, including iron, zinc, and cadmium transport and accumulation, as well as iron deficiency tolerance and response. It is linked to photosynthetic rate, chlorophyll and carotenoid content, leaf chlorosis, stomatal resistance, germination rate, and plant growth and development traits. Additional associations include pollen germination, cellular response to hypoxia, response to bacteria, downregulation of abscisic acid signaling, and localization to the plasmalemma, endosome, and ESCRT I complex. Related genes in other species connect the family to iron uptake, transport, and translocation, as well as nickel and cadmium accumulation.
